Two `20g` worms climb over a `10cm` high, very then wall. One worm is thin and `20cm` long the other is fat and only `10cm` long. What is the ratio of the potential energy (w.r.t. the base of wall) of the thin worm as comparses to that of the fat worm when each is half way over the top of the wall as shown?

Aladder of 5 m long rest with one end against a vertical wall of height 3 m and the other end on the lower ground. If its top slides down at the rate of 10 cm/sec, find the rate at which the foot of the ladder is sliding.

Two straight thin bars, one of brass and the other of steel are joined together side by side by short steel cross-pieces at 0^(@)C , one cm long, the centre lines of the bars being one cm apart. When heated to 100^(@)C , the composite bar becomes bent into the arc of a circle. Calculate the radius of this circle. alpha for brass = 19xx10^(-6)per""^(@)C,andalpha for steel = 11xx10^(-6)per""^(@)C ,
